a) Proof by contradiction is different from traditional proof as it accepts a single example showing that a statement is false, instead of having the need to derive a general relationship for all input values.
b) The statement is true by contradiction as the sum of the measures is of 160º, and not 180º.
<h3>What are supplementary angles?</h3>
Two angles are called supplementary angles if the sum of their measures has a value of 180º.
The measures of the angles in this problem are given as follows:
Then the sum of the measures of this angles is given as follows:
90 + 70 = 160º.
Which is a different sum of 160º, confirming the statement that the angles are not supplementary by contradiction.

Simple interest is given by:
S.I.=(PRT)/100
where:
P=principle
R=rate
T=time
from the question:
P=2681.04
R=13%
T=12 months=1 year
thus;
S.I=(2681.04×1×1.3)/100
=$34.85352
The total amount payable will be:
Total amount=principle+interest
=34.85342+2681.04
=$2715.90 This is approximately equal to $2,710.08
Answer:
There are as many definitions of empire as there have been empires, but some pretty familiar elements appear in most of them. It starts with working on our “control issues”.
Answer:
(13, 9)
Step-by-step explanation:
Make an equation for the line.
y = 0.5x + b
5 = -3.5 + b
b = 8.5
y = 0.5x + 8.5
Plug them into the equation.
(-13, 9) 9 ≠ -6.5 + 8.5
(-9, 13) 13 ≠ -4.5 + 8.5
(9, 13) 13 = 6.5 + 8.5
(13, 9) 13 ≠ 4.5 + 8.5
686 barrels left. If I'm not mistaken this should just be simple subtraction
